Question

Trimmer blades fall under two main styles which are

Answer 1

Trimmer blades can be categorized into a three-blade design and a single/multi-blade design. The three-blade design is more efficient and safer, while the single/multi-blade design may have higher tip speed and varying efficiency. The rotation mechanism of the blades allows them to engage the wind at different angles, further affecting their efficiency.

Step-by-step explanation:

Trimmer blades fall under two main styles: three-blade design and single/multi-blade design. The three-blade design is considered the most efficient and safer than the single/multi-blade designs. According to Figure 12.4, the three-blade design has a lower tip speed and is therefore less dangerous.

The blades of a trimmer are similar to long airplane wings and are mounted so that they can be rotated on an axis running the length of the blade. This allows the blades to engage the wind at any angle, resulting in varying efficiency.

1. Three-blade design: This design is the most efficient and safer due to its lower tip speed.
2. Single/multi-blade design: This design may have a higher tip speed and may not be as efficient or safe as the three-blade design.
3. Blade rotation: The blade rotation mechanism allows the blades to engage the wind at different angles, increasing or decreasing efficiency accordingly.
